Patients with renal failure can have early fistulization and early fistulization is advocated.
Patients with chronic renal failure who have not progressed to uremia do not need hemodialysis treatment for the time being, and if they need renal replacement therapy in the later stage and choose hemodialysis, they can have arteriovenous fistuloplasty in advance.
Most of the patients with renal failure need long-term dialysis treatment in the late stage, and arteriovenous endovascular fistula is an important access for hemodialysis treatment, which can only be used after 1~3 months after surgery. It takes 1-3 months after surgery before it can be used. Prepare the endovascular fistula in advance and use it directly when dialysis is needed. If an endovascular fistula is not prepared in advance, long-term or temporary catheter dialysis, peritoneal dialysis, etc. will be needed when dialysis is necessary.
More and more patients with chronic renal failure choose hemodialysis, so the arteriovenous endovascular fistula is very important, it is recommended that patients with renal failure to regular hospitals to complete the surgery, and after the operation need to pay attention to protect the forearm on the side of the fistula.
